Vortex+ Morphun: Careful!

Vortex+ Morphun: Careful!

Suppose I have a Morphun, Vortex deck. I play my Vortex card with 3 pills and lose, with Morphun's ability, I should have 9 (pills that I have left) + 2 (Vortex bonus) + 1 (Morphun's ability) = 12 Pills, but it won't be 12, it will be just 11. I think when Vortex loses a round, Morphun's ability is not taken into consideration. But when Vortex wins, I have noticed, all is fine. Why?
